To all whom it may concern:

Be it known that I, ADELMER M. Barns a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Valve-Bag-FillingMachines, of which the following is a specification.

My invention relates to improvements in bag filling machines, and hasfor one object to provide means for removing the filled bag from thefilling relation, and discharging it to a conveyer or suitable means fordisposing of it. Means for discharging or moving are preferably operatedby the hand of the operator.

I have illustrated those parts of a bag filling machine particularlyadapted to filling valve bags, although it is obvious that other meansfor actuating the discharge or removing device may be used, and thedevice might be applied to other types of bag fillin machines.

My invention is more or less illustrated diagrammatically in theaccompanying drawings, wherein- Figure 1 is a side elevation in partsection.

Fig. 2 is a section along the line' 2-2 of Tig. 3 is a diagrammaticfront elevation of part of the machine.

Fig. 4 is a diagrammatic side elevation in part section of a portion ofthe machine to show more clearl the relation of the parts.

Like parts are indicated by the same letter in all the figures.

A is a supply hopper, A a supply passage leading therefrom adapted topermit the passage of material to the propeller housing A, from whichthe material is projected by the propeller wheel A, through the feedinthroat A. into and through a bag filling tu e A. All the parts exceptthe tube A" are fixed in relation.

B is a scale beam. At its outer end it has a knife edge B upon whichrests an A frame B The A frame is supported on the scale B, and guidedat its top by the link B pivoted on the hopper A. ThlS A frame Bsupports the filling tube A, and has pivotally mounted thereon a bagholding latch B serrated at its lower end in engagement with the bag Bas it hangs upon the tube A: B .is a trip lever pivoted on the latch Bfree to swing with respect to the latch in the direction opposite to thedirection in which the latch itself is free to swing.

C is a cradle having an L-shaped bottom C whose outer end is pivoted asat C on,

the A frame B (3 is a bag chair adjustable along the cradle C, by meansof the pin (1*, which may be made to engage in one of the notches C inthe cradle itself. C is a breast-strap or late surrounding a portion ofthe bag, and so positioned that, as the bag hangs normally in thefilling position, its inner side just touches this strap. 0'' is adumping handle attached to the'upper end of the cradle C by means ofwhich the operator may easily manipulate the cradle.

D is a bagreleasing wiper immediately below the handle 0. It is adaptedto engage the lever B when drawn out to tilt the ba latch 18*, and whenthrust back, adapted to ride over such lever to permit free return ofthe partsto their previous osition without interference with or by theag latch.

t will be evident that while I have shown in my drawings an operativedevice, still many changes might be made in size, shape and arrangementof parts without departing materially from the spirit of my invention.

Attention is called to my copending application Serial Number 4097,filed January 25, 1915, which shows an arrangement somewhat similar tothat illustrated in the present application. Certain novel featuresshown but not claimed in this application are claimed in that one.

The use and operation of my invention are as follows The bag is firstsuspended upon the filling tube with the parts in the position shown inFig. 1, the lower portion of the bag resting upon the chair. Thematerial is then discharged into the tube until the bag is filled. enthe bag is filled, the scale then operates in any suitable manner, orthe feed supply is cut off in any suitable manner, neither of which ishere illustrated, and the operator is then prepared to discharge thebag. He does it by seizing the handle and giving it a smart pull towardhim. As it moves, 1t first exerts pressure on the bag,

then releases the bag holding latch, and then discharges the bag. Thepoint is that the breast strap first applies pressure to the .bag at theupper end to tip it out away from its filling position, and that thechair is then tipped up and out to throw the bag. The

. result is that the bag is thrown into the position shown in dottedlines in Fig. 1 where it may rest upon the conveyer or platform, asindicated, and it is effectually thrown away from any position in whichit might interfere with the weighing or the manipulation of the bags.The chair may be moved up and down to accommodate for varying lengths ofthe bag, and by this arrangement, the heavy, stiff and rough bags areevenly and rapidly discharged w thout injury to the operators hands, andwithout delay or danger of tearing the bag.

The cradle is pivoted to the A frame at a point in front of the centerof gravity of the bag, so that as the cradle is rocked, it tends to liftthe bag from below, and when the operator jerks it smartly thebreast-plate first rocks the bag from above and the chair catapults itfrom below and tips or swings it so as to throw it clear away from themachine.

In Fig. 4: the cradle is shown in a position which it would never occupymerely for the purpose of making clear its shape and arrangement. Theoperator will, under ordinary circumstances, never carry it any fartherthan in the position shown in dotted lines in Fig. 1, but of course itis free to move clear down should this become necessary or desirable.

It will be understood that by my arrangement I first rotate the packageabout its base by means of a package moving member, which, as noted, isimmediately below the filling tube or fixed package support, and then Ibodily throw the package upwardly and forwardly, thus completing itsrotation and permitting or causing it to draw intoa position of rest atright angles to and altogether removed from that position which itoriginally occupied, and my movable package support at the bottom actsas a catapult to project or throw the bag away from its originalposition, so that it assumes the subsequent position.

I claim:

1. In a package filling machine a fixed package support and means forlocking the package thereupon, a pivotally mounted cradle having amovable package support.

a package moving member, and a lock releasing member all carriedthereby.

2. In a package filling machine a fixed package support, a pivotallymounted cradle, a movable package support, and a package moving means,both carried thereby.

3. In a package filling machine a fixed package support and means forlocking the package thereupon, a pivotally mounted cradle having amovable package support, a package moving member, and a lock releasmmember all carried thereby, said cradle being pivoted at a point forwardof the center of gravity of the loaded cradle.

4. In a package filling machine a fixed package support, a pivotallymounted cradle, a movable package support, and a package moving meansboth carried thereby, said cradle being pivoted at a point forward ofthe center of gravity of the loaded cradle.

5. In a package filling machine a fixed package support, a pivotallymounted cradle, a movable package support, and a package moving meansboth carried thereby, said package moving means being adjacent thepackage support and adapted to draw the package from the support.

6. In a package filling machine a fixed package support'and means forlocking the package thereupon,'a pivotally mounted cradle having amovable package support, a package moving member, and a lock releasingmember all carried thereby, said movable support being adjustably mouned on the cradle.

7. In a package filling machine a fixed package support, a pivotallymounted cradle, a movable'package support, and a package moving meansboth carried thereby, said movable support being adjustably mounted onthe cradle.

8. In a'packa e filling machine means for holding the pac age in asubstantially vertical position, means for releasing it and swinging itabout a line perpendicular to its axis and means for simultaneouslybodily throwing it upwardly and outwardly.

9. A package filling machine comprising a filling tube adapted to enterthe package, means for locking the package in position thereon, asupport for the lower end of the package, a pivoted frame carrying saidsupport, means carried by it for withdrawing the package from thefilling tube and means for releasing the package locking means.

10. A package filling machine comprising a filling tube adapted to enterthe package, a support for the lower end of the package, a pivoted framecarrying said support, and means carried by said frame for withdrawingthe package from the tube.

11. A package filling machine comprising a filling tube adapted to enterthe package, means for moving the package laterally along the tube awayfrom the filling relation, and simultaneously operated means en.- gagingthe bottom of the package for throwing it upwardly and outwardly todischarge it from the machine.

12. A package filling machine, an A frame, a package filling tube uponwhich the package is mounte a cradle pivoted on the frame, means forsupporting the bottom of aaaaeen the ackage on the cradle, and meanscarried y the cradle for withdrawing the package from the filling tube.

13. A package filling machine, an A frame, 6 a package filling tube uponwhich the package is mounted, a cradle pivoted on the frame, means forsupporting the bottom of the package on the cradle, means carried by thecradle for withdrawing 10 from the filling tube,
